Specification of Letters Patent.

Patented Feb. 21, 1922.

Application filed February 6, 1920. Serial No. 356,781

(GRANTED UNDER THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. In, 1313.)

T0 all whom it may concern:

' Patent N 0. 112,07 8,) of which the following is a. specification.

V This invention relates to machines for opening all kinds of thread work, cotton, woollen, worsted, rags and the like, of the type in which a toothed cylinder or swift revolving in a casing receives from feed rollers the material, which then passes part- 1y around the cylinder, between the cylinder and the casing, this operation being usually repeated in a set of several successive scutchers or opening machines in series.

According to my invention I secure to the inner surface of the casing under the cylinder a metal segment having six or other number of ribs, between which ribs I secure to the segment toothed lags, the teeth on which are just cleared by the teeth of the rotating cylinder. The cotton or' the like in travelling through the machine is thus exposed to the combined action of the stationary teeth on the segment and the revolving teeth of the cylinder, and the lower layer ofthetravelling cotton not being shielded from teeth by the upper layer as before, the opening effect is so much increased that the operation can be performed as well by a series of a less number of cylinders or swifts as it has previously been by a greater number. A great economy in plant, floor space, and motive power is thus eflected. Further the finished material is of much more value owing to the preservation of the staple and the avoidance of neps'and knots. A trough or tray is fixed slightly beyond the vertical plane of the centre of the cylinder, and the further edge of the said trough, or the flange of the machine casing in which the said troughslides is slightly higher and. at a slightly less radial distance from the centre of thecylinder than the edge of the rib on the above named segment which is next to the'trough, this arrangement allowing the most effective action of the trough.

Such being the nature of the said inven tion, in order that the same may be clearly understood I have hereto annexed a diagram illustrating the arrangement of the parts mentioned.

The reference numeral 1 indicates a portion of the large swift, 2 2the feed rollers, 3 the usual knife below the feed rollers, the upper wearing face of which knife I preferably form on a renewable edge piece or bead 4. A metal segment 5 having ribs 6 is secured by brackets 7 to the under-casing of the machine (not shown) and between these ribs 6 are secured lags 8 provided with teeth opposing the teeth on the swift. By this arrangement the toothed lags are prevented from working loose in such manner as to interfere with the proper action of the machine.

The sliding trough or drawer tooth trap 9, which can be drawn out at the side of the machine from its guides 10, has its further side 11 arranged as shown to form a cliff against which are thrown loose teeth, broken pieces of lags, pins, screws and other hard materials, which then fall back into the trough.

I claim 1. In an opening machine, a revoluble toothed cylinder, feed mechanism for supplying material to "be treated, a stationary segment'arranged below the feed mechanism and provided with ribs, and toothed lags arranged between the said ribs and co-acting with the said cylinder to treat the material fed between them and the cylinder.

2. The combination, with an opening machine constructed as set forth in claim 1, of

a removable receptacle for catching hard rubbish discharged with the treated material, said receptacle being arranged at the lower end of thesaid segment under the 7 said cylinder.

In testimony whereof I afiix my si nature.

HENRY HIRST written.
